Application filed December 11,1916. Serial No. 136,254.

' Mountings, of which the following is a specification. My invention relates to improvements in ophthalmic mountings and has particular reference to an improved form of mounting or frame of what is commonly termed the combination type, that is to say a mounting made up of combined metal and zylonite or other non-metallic parts.

One of the leading objects of the present invention is the provision of a novel and improved construction of frame making use of improved means for uniting the metallic and non-metallic parts.

A further object of the present invention ,is the provision of an improved construction of frame of this character in which the nonmetallic material encircling the lens shall be split at least at one point to facilitate inscr tlon and removal of the lenses.

A further object of the invention is the provision of a mounting of this character in which the greater portion of the metal of the frame shall be so covered as to prevent it from coming into contact with the face of the wearer, thereby rendering the frame as a Whole much more comfortable to Wear than is the case when the metallic parts are in contact with the flesh and at the same time preserving the durability and adding to the apgearance of the mounting.

ther objects and advantages of the invention include the simplification and improvement of the details of construction of the several parts going to make up the completo mounting, and should be r adilv apparent by reference to the fullon ing specification taken in connection with the accompanying drawings forming a part thereof, and it will be understood that T. may make anv modifications in the ccific details of construction shown and .escribed within the scope of the appended claims \vithout departing from or in anywisc exceeding the spirit of my invention.

Figure T represents a front view of an mproved monnting embodying my several improvements.

Fig. H represents a fragmentary detail View of one style of metallic part therefor.

Fig. III represents a fragmentary detail. sectional view illustrating one manner of connecting the end of the z vlonite to the frame.

Fig. IV represents a sectional view taken on the line IV---IV of Fig. 1.

Fig. V a similar sectional View on the line V-V of said figure.

Fig. VI represents a side elevation of one form of temple bearing a non-metallic covcring.

Fig. Vll' represents a sectional view as or the line VII-VII of Fig. VI.

Fig. VIII represents a fragmentary View illustrating one form of my split non-metallic lens rim.

Fig. IX represents a. similar view illustrating another form of combined metallic and non-metallic split lens rim.

F ig. X represents a view of a modified temple construction.

Fig. XI represents a sectional View taken as on the line XI-XI of Fig. X.

Fig. XII represents a view of another form of temple.

Fig. XIII represents a sectional View thereof on the line XIII--XIII of Fig. XII.

Fig. XIV represents a side elevation of a further modification of my temple construction.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views. the numeral 1 designates the spectacle bridge or center for connecting the lenses, in the form shown in Fig. I the bridge ends hcing scoured as by soldering to the metallic lens frame 2. and continued inwardly in the clip fingers or clip 3 adapted to be bent around and clampinglv secure in position the inner portion of a zylonitcor other nonmetallic frame memberi as illustrated in Fig. V for example. This frame member 4 is preferably formed with the channel 5, into which the metallic frame fits and has its end split and secured to suitable end pier-cs to facilitate insertion and removal of a lens from the frame.

In the form of the invention illustrated in Figs. I and H, I have shown the metallic im 2 as encircling the lens and terminating llli" the nd pier 6 and 7.

in Fig. 'lll, I have illustrated, however, a. cnnstrnctii'in in which the central metallic rim or me member is dispenser l with and the and pieces are provided with the embracing yoke or car portion 9, clampingly en gaging the en-l of the zylonile to secure the mid pier-es i'l rrto, while in Fig. TX, I have again illnstratrd the use of the metallic frame it inning secured to its ends the end pirrrs ti :2 l 7, which and pieces have scrurvd viilwr directly thereto or as: a part of and through the medium of the frame 3, the mnhraving fingers or clamp 10, which extrinl around the art-mite at or adjacent its loan end, and serve to grippingly or clampingl'y anilithe and pieces thereto to hold the zyionitc closed around the lenses 11 when the latter are in position Within the frame.

lnginv event the main essential characteristic will he wilted that is to say, that the aylonite rim instead of being continuous in the usual manner, with the lenses sprung lherrlni'o. is split at the outer side but pref-- erahly lornn-d without heavy outwardly extending terminal ends or the like. detracting from t. eornamental appearance of the nioonting. and in place of such ends that metallic end pieces; are employed suitably ioinod togrthrr. as by the connecting screw 22. to c z'inert tin" end pieces. and these 0nd plows are united h suitable gripping or clumping-j m mhrrs to the ends of the rionititin-int: and thus serve to satisfactorily retain inn zylonito or non-metallic frame in position ahout the lenses, either with or without, the interposition of the metallic rim or zylonitrlinrr 2.

To :nlditiona ly increase the desirability of my lrnior and to -anse the several parts to snl' slantinlly correspond and be constrnctml in the neairst and most practical and durable manner and to facilitate ready ndiiislnni-tit oi the several parts of the nnnmiii. l prvlvralily provide :15 part of the w ph-te i'rame. my improved tern- {alt-i, win-ii like the frames, may haw the haw or lumnlntlmi oorl rm i l and the zylw old or non'nwtaliii: portion ll. tine i'urni of this mnsitrnrtiiin has horn illustrated in Figs. \'l and Vll. in wiiirh the zylonile lnh; hwn formed of rhannri construction, in the nuic manner as the portion -l used to nncirrio tin.- lrnscs and receives the metallic part 13 within the channel. Qnitahle clips 15, which in Fig. Vll are illustrated as being soldered or secured to the temple wire 13, are shown as partially embracing and clampingly 0r grippingly engaging and srcuring the zylonite in position in the same manner that the clip fingers 2i and 10, illns' rated in Figs. l. and lX, serve to clampm l secure the portion -l in position.

igs. X and XI illustrate a slight modi iication of this constrw'tion, in whirh in place of the clamping fingers liiting prongs 16 are employed to retain the nonnn-tallic member in position, ferrules l? heing shown for a similar purpose in Figs. Xll and XIII, while clip lingers 18 on the non-metallic member clampingly engaging the metallie member, are illustrated in Fig. Xll", the purpose in all instances be ng the satis factory securing ot' the \nnrmetallic to the metallic member.

From the foregoing; specilii-ation tahen in connection with the accompanying d 'awings, the constrw-tior and aduintages of my improved combined n al and rmn'metallic frame should he readily apparent, and it will be seen that I have provided an improved frame which will present a neat and attractive appearance on the face, which will comprise the split zylonite rims having their ends detarhalily secured one to the other by nrnt and imionspirnnns mrtnllic end pieces, thin; 't'avilitating the insertion and removal of the lenses in a well known manner, Without thineccssity ct' prrnliar and special construction or heavy and ungainly parts, and

it will be further noted that in my improved framel form the major visible portion thereof of a clean, sanitary and comfortable feeling, and nntarnishahle non-metallic composi tion, with the working parts, such as temple ends, and pieces. bridging member, and the like, formed from metallic material which will present a neat appearance and will be of less size for correspondingly desired strength, but that l place, as on the temples and metallic lens rims, if employed, a corering of the non-metallic covering, which will feel soft and comtortahie when engaging the fare, and will remove the liability of undue wear and tarnishiinz ol' the ordinarily thinly covered goldhllnl material cnstmn aril employed for these purposes.

I claim:

1, in a mounting of th character de scribed, the combination with a metallic hridge. of metnllir lens frames secured thereto and having interior grooves to receive a lens and non-nn-Lallie tranws having ('l\l1'(1- ncls receiving the metallic frames, said non metallic Frames encircling the metallic frame, and having their nods; secured to the ends of the metallic frames lay threaded Fastening devices.

In an ophthalmic mounti g, the combisupplemental fin nation with a metallic frame embracing a lens, said frame being split at one side and having end pieces secured to its ends and extening outward! therefrom, of a nonmetallic rame memher having a channel receiving the metallic frame member and extending around said frame member, and threaded fastening devices passing through the end piece sections and into the ends of the non-metallic frame member for ti htening said ends against the end pieces an positively securing the non-metallic frame in position around the metallic frame. 3. In an ophthalmic mounting, the combination with a' bridge, of metallic frames secured thereto and adapted to directl engage the lenses, said frames being 5 it at one side and provided withsuitab e and pieces, a non-metallic frame fittiirg- I hd IQ the metallic frame and terminatin v the end ieces, fasteningfdcrices;

through t e end pieces and e ends of the non-metallic frame-fer sm sh it in position about the meta lic frame-{an rs carried byjhefmetallic frame and encirc ing the non-metallic frame for supplementing the acticn of said fastening devices in positiyely securing the pflts together. I i 1 4. In an o hthalmic mounting, the combiiiation with a metallic lens encircling rim having laterally extending connecting plates or,end pieces secured to its ends, Sitld end pieces having apertures formed therethrough immediately adjacent their oints l of attachment to the metallic frames, 0 nonmetallic frames encirclin the metallic frames and having channe s receiving and concealing said metallic frames, said nonetallic frames terminating at and abutting t e outer faces of the connecting plates or end pieces and overl ing the apertures there-"g in, and fastening evices each engaged in one of the apertures and projecting therethrough into engagement with the adjacent end 'of the non-metallic frame member to firmly secure the non-metallic frame member to the connecting plate or end iece and lock the metallic frame member wit in the groove of the non-metallic frame member, substantially as illustrated.

5. In an ophthalmic mounting, the combination with a metalliclens receiving frame for direct engagement with the lens, of a non-metallic frame surrounding and confirth cealing the metallic frame, the said metallic and non-metallic frames being split at one side to facilitate insertion or removal of the lens and fastenin devices securin the ends of t c non-metal 1c to the endso the metallic frame to securely unitethe two frames.

In testimony whereof I affix my signature in the presence of two witnesses.
